Fig. 2 is the partial structurtes schematic diagram of the utility model embodiment.
Fig. 3 is the handle rotating mechanism and the schematic diagram that concerns of strengthening driving member of the utility model embodiment.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Extremely shown in Figure 3 according to Fig. 1, high-strength mechanical formula door lock described in the utility model, it comprises housing 1, be installed on housing 1 the dead bolt controlling organization and for the handle rotating mechanism of door lock handle interlock, the handle rotating mechanism drives in the door lock hole of dead bolt controlling organization on housing 1 and stretches out or retract.Wherein, described handle rotating mechanism comprises the steel-molded handle tumbler 2 of one, elastic component 3, handle tumbler 2 has the dwang 4 with its integrated molding, dwang 4 is connected with the dead bolt controlling organization, elastic component 3 is set on handle tumbler 2, and the fixed end of elastic component 3 is located by connecting on housing 1, and the fixed end alive of elastic component 3 is connected on handle tumbler 2 opening sidewalls.By the setting of elastic component 3, make postrotational handle tumbler 2 energy Rapid resets, transmission stability is strong.And handle tumbler 2 is integrated steel-molded, and the handle rotating mechanism that it effectively replaces original split type upper rotation iron plate, Rotational Cylindrical, lower rotation iron plate to combine is strengthened the intensity of rigidity, the phenomenon of Reducing distortion greatly.
With reference to Fig. 2 and shown in Figure 3, described housing 1 is provided with reference column 5, projection 6 and block 7, and reference column 5, projection 6 and block 7 are fixedly installed in respectively on housing 1, and the three forms the bikini reinforcing elements of unloading power for the handle rotating mechanism.Prioritization scheme of the present utility model is that this reference column 5 and the adaptive flexible connection of handle tumbler 2 also are fixed on housing 1, and the fixed end of reference column 5 and elastic component 3 is located by connecting; Projection 6 also is fixed on housing 1 with the adaptive flexible connection of dwang 4 of handle tumbler 2, and block 7 is with the adaptive flexible connection of dead bolt controlling organization and be fixed on housing 1.Wherein, described dead bolt controlling organization comprises dead bolt 8, connecting axle 9, limited block 10 and return unit 11, dead bolt 8 is connected on the top of connecting axle 9, connecting axle 9 is adaptive to be installed on limited block 10, between return unit 11 is set on connecting axle 9 and is connected on the top of the end of dead bolt 8, limited block 10.And, connecting axle 9 ends are provided with the fixture block 12 that is fixedly connected with the dwang 4 of handle tumbler 2, by swing handle tumbler 2 make the connecting axle 9 that is connected with fixture block 12 pull dead bolt 8 to stretch out or the door lock hole of retraction on housing 1 in, if the end retraction of dead bolt 8 in the door lock hole of housing 1 and the top be pressed on the end of block 7.
That is, during opening door lock, apply external force to door lock handle, drive the handle rotating mechanism and rotate, the dwang 4 of handle rotating mechanism pulls connecting axle 9 to move backward, under the effect of limited block 10, and compression return unit 11, thus pull dead bolt 8 to retract in the door lock hole.At this moment, adaptive being connected on reference column 5 of handle tumbler 2 that one is steel-molded, dwang 4 is connected on projection 6, block 7 top is pressed on the end of dead bolt 8, this connecting terminal of 3 effectively will pass to the external force of hydrogen hand rotating mechanism to be disperseed to unload power, makes reference column 5, projection 6 and block 7 form the bikini reinforcing elements of unloading power for the handle rotating mechanism, strengthens the external force that low anti-heavier external force is exerted pressure, thereby realize reaching international external force testing standard, guarantee the normal use of product.When closing door lock, under the mating reaction of elastic component 3, return unit 11, handle tumbler 2 is resetted and move apart reference column 5, make simultaneously dwang 4 move apart projection 6, and connecting axle 9 is pulled and moves forward, thereby make dead bolt 8 move apart block 7 and stretch out the door lock hole, stable, practicality is high.
In addition, in preferred version, with reference to shown in Figure 3, set up on handle tumbler 2 and strengthen transmission tumbler 13, strengthening adaptive being fixedly installed in of driving member 13 also can be along with handle tumbler 2 rotates and rotate on handle tumbler 2, and strengthen the connecting rod of driving member 13 and the adaptive installation of connecting axle 9 of dead bolt controlling organization, further strengthen rigidity intensity and transmission stability energy.
Above-mentioned specific embodiment is only the utility model effect specific embodiment preferably, and all or high-strength mechanical formula door locks of being equal to identical with this structure are all in the application's protection domain.
